Attic Fans - are they worthwhile?
The contractor who installed a dark shingle roof on my home suggested the installation of an attic fan for $285. It vents through the roof, pumps about 1200 cfm and supplements the convective air movement of the soffets and ridge vents. He said he sets the thermostat so it kicks on at 105 degrees and will lower the garage temperature by about 15 degrees.
So, does anyone have any experience to indicate whether these attic fans are worthwhile or not?
